Lady Gaga is handling her critics with class. This week, the pop star faced some ridicule after looking a bit heavier than usual while performing in Las Vegas Saturday. At the MGM Grand Garden Arena, the 28-year-old filled out her costumes, and showed off a much curvier figure than the one she had when she shot to fame in 2008.

On Monday, Lady Gaga responded to the criticism by posting a black-and-white photo of herself on Instagram. Sitting on a car in a white fur coat and stockings, she has a simple caption, “Curvy and proud.” The picture has received more than 135,000 likes from fans.

While donning a number of different outfits for her performance, Gaga looked a bit wider than she has in the past, causing some fans to snipe. “This isn’t sexy, this is FAT,” wrote @gagatuvoz. “Gaga is over, she is fat, katy [perry][is] better than her,” wrote @boraabora.

This certainly is not the first time Gaga has been "fat-shamed." In 2012, the media criticized the singer after she gained 25 pounds. In response, she started a campaign urging her "little monsters" all over the globe to be brave and accept their bodies, regardless of excess weight, scars and other "imperfections."

"Today I join the BODY REVOLUTION. To Inspire Bravery. And BREED some m$therf**king COMPASSION,” Gaga wrote on her official website, after posting pictures of herself in a bra and underwear. "This profile is an extension of that dream. Be brave and celebrate with us your 'perceived flaws,' as society tells us. May we make our flaws famous, and thus redefine the heinous,” Lady Gaga added.
